Carthage update fails while building Polyline scheme

When I run scripts/setup.sh I get the attached Build Failed message.

I wonder if this is the culprit in Line 334 of Polyline.swift. In function extractNextChunk, line 334 causes the build error 'subscript' is unavailable because it was obsoleted in Swift 4. StackOverflow suggests this fix to your exact MapBox code:

Actually Polyline has already been updated to Swift 4 so your Cartfile dependencies should point to that:
https://github.com/raphaelmor/Polyline/tree/v4.2.0
or rather, MapboxDirections dependencies should point to that. I've raised an issue in MapboxDirections.

MapboxDirections dependencies should point to that

Looks like that will happen in mapbox/mapbox-directions-swift#196

I get the attached Build Failed message

I think MapboxDirections.swift at "v0.11.2" should still work. I'm not able to reproduce the issue you have when I try with Xcode Version 9.0 (9A235) and Carthage v0.26.2. In my log I see:

Can you try clearing the Carthage Build and Checkouts folders in your project also and the derived data in from the directory noted in the log you attached (/Users/wa/Library/Caches/org.carthage.CarthageKit/DerivedData/)?

[wangela]

Hm, cleared Carthage/Build and Carthage/Checkouts and Derived Data. Ran scripts/setup.sh again, got same errors. Same xcode, same carthage versions.
